ZP error log: Active tab of instance not found

[shabbysquire]

Keep getting this error message in ZP:

bef4f45b-f30c-4418-8f29-0ee9f6ed7a36 Run Web browser tab setting. Active tab of instance not found.

I'm sure this has something to do with the timeout tab I'm using, but not sure.

I've also noticed a few threads in ZP get 'stuck' on a page and nothing happens. Is there any way to abort that particular thread if it happens again?

This can happen if you don't have enough free resources for your PC. If you have many other programs working in the background.

Also check of your windows was updated. Maybe NET 4.5 was installed. Then remove it.

I've got .Net 4 framework client, and also.Net framework Extended. Does the Extended count as .Net 4.5?

Attach a screenshot of insatnce settings. Also it can occur due to anti-virus when it blocks instances.
